It is always an appropriate time of year to discuss the liturgical year with your students. Depending on the age of the students you teach, you can adapt the information to share.
The Liturgical Year is marked by special seasons: Advent, Christmas, Lent, The Triduum or Three Days, Easter, and Ordinary Time. The Liturgical Year begins on the first Sunday of Advent, which usually occurs around the beginning of December or the end of November, and ends on the feast of Christ the King. On Sunday, May 19, the Church celebrates Pentecost. Pentecost marks the end of the Easter season.
Unlike our traditional 365-day calendar, the purpose of the Liturgical Year Calendar is not to mark the passage of time, but to more fully celebrate and understand the entire mystery of Jesus Christ, from his Incarnation and birth until his Ascension, the day of Pentecost, and the expectation of his return in glory. During the course of a year, the Paschal Mystery—the Passion, Death, Resurrection, and Ascension of Jesus—is viewed from different angles, in different lights.
In the account of the first Pentecost, the Holy Spirit descended upon the disciples and empowered them to do mighty deeds in God's name. We are called to share in the Church's mission to spread the Gospel of Jesus to others.
